The invention has relation to calculating machines for performingproblems in addition, subtraction, multiplication and d ivision, andregistering the results, an object being to provide a machine having aplurality of series or banks of denominational keys and wherein a singleoperating device dle upon shaft 14, saic f actuating elements or vunegeneral rack type,

f stroke. A further object is to provide se- Other objec-ts andadvantages jwill hereinafter appear.

The invention consists in the novel coni struction and combinations ofparts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2designates the casing; 3 the numeral keys, arranged in a plurality ofdenominational series each from 0 to 9 inclusive; d a rear transverselysliiftable carriage, pivoted to the casing at Ll; 5 a series ofregistering wheels upon shaft 6, said shaft having bearings in saidcarriage; 7 a second series of registering wheels, upon the same shaft6; 8 a series of carrying dogs or pawls upon shaft 9; 10 a series ofselecting or dierential actuating elements, one selecting element foreach series of numeral keys, said elements being rotatably fast andslidable upon shafts 10'; 11 a series cf intermediate gear wheels uponshaft 12, said gears operating the registering wheels and being actuatedby the selecting` elements and also by the carrying dogs; and 13 is anoperatinor device or crank lian- I handle operating the selectingelements and the carrying mechanism.

15 is a series of longitudinal levers, pivoted or fulcrumed respectivelyat their rear ends at 16 and engaged by shoulders 17 of the numeral keystems 17 there being one lever for each denominational series of keys,the different key stems of the same denominational series being spacedfrom the fulcrum of the corresponding lever by varying distances, toaccomplish a greater or less depression of the lever, according to thevalue of the key depressed. The key stems in any denominational seriesare Vheld down by a spring-pressed bar 19,

common to the series and pivoted at 20, said bar engaging shoulders 2lof the key stems for this purpose, and the levers 15 being held down bythe depressed keys.

The levers 15 have respectively engagement with vertical racks 10,engaging pinions l1 of the shafts of the selecting elements, to cause,in the depression of said levers, an axial rotation of said elements,each element being turned more or less, according to the value of thekey depressed, as previously explained.

The shafts 10 of the selecting elements are mounted in a frame 21,pivoted forwardly at 22 and adjustably supported in rear by shafts 23,said shaft carrying a cam 24, whereon bear at opposite points rollers 25of said frame, whereby, for each rotation of said shaft, the frame israised from normal depressed position, raising the shafts 10 and theselecting elements into position to rotate the intermediate gears 1l,upon sliding movement of said elements upon their shafts, the frame andthe selecting elements being normally in lowered position, for reasonsstated hereinafter.

The shaft of the loperating handle is provided with a bevel gearconnection 26 with a longitudinal shaft 27, said shaft having bearingsin the casing or base and being provided with a double cranked portion28, including an inclined part 29, a transversely extending arm 30 atone end thereof loosely engaging said inclined part and at its oppositeend engaging a reciprocatory slide frame 31, by means of a universaljoint 30', the frame having rollers 32, working in guides 33 of thecasing whereby upon operation of the shaft 27, brought about by a halfturn of the crank handle, the inclined. part 29 of said shaft is causedto assume an opposite inclination and to move said arm and the slideframe rearwardly or forwardly, as the case may be, and thereby, owing tothe engagement o f the endmost teeth of the selecting elements withslots 34 of a transverse extension 35 of said frame, to move all of theselecting elements longitudinally upon theirV shafts.

The selecting elements are each provided with nine teeth, starting allfrom the same radial position relative to the element and beingcontinued around the element to varying degrees, gradually increasingfrom one end to the other, a longitudinal blank or untoothed space beingleft between all of the teeth of each element, so that, in the sliding`movement of the elements, those not previously axially turned byoperation of the numeral keys will have no action upon the correspondingintermediate gears.

The shaft 27 has at its rear end bevel gear connections 36 with atransverse shaft 23, the latter shaft having spur gear connection 38with the carrying shaft 9, and turning the carrying shaft four timesaround for each turn of the crank handle.

In performing addition and multiplication, the operating handle isturned clockwise once completely, to thereby move the frame 21 and tomove the selecting elements longitudinally upon their shafts, fromnormal lowered position, midway of the lengths of their strokes, toraised position, at the forward end of the strokes, then rearwardly tothe opposite end of the strokes, and then to return said elements tonormal position, the carrying being performed while the elements are soreturned, in the same clockwise movement of the handle; and inperforming subtraction and division, the handle is turnedcounter-clockwise once completely, to move said frame and to move theselecting elements from normal position to raised position, at the rearend of their strokes, then forwardly to the opposite end of the strokes,and then to return the elements to normal position, the carrying beingperformed as stated, while the elements are so returned.

In order that said elements shall be returnable backwardly or forwardly,as the case may be, without actuation of the intermediate gears by thoseelements that have been axially turned, it is necessary that, after theelements have been moved longitudinally, as stated, they shall belowered and then returned, so lowered, to normal position. And inasmuchas the selecting elements are movable eith-errearwardly or forwardly,according to the nature of the problem, and as the carrying is performedafter the elements are so moved, it is necessary that they shallnormally be located in lowered position, midway of the ends of theirstrokes.

The numeral keys are first depressed as required for the particularproblem, the levers 15 being at the same time depressed to varyingdegrees, as stated, and the selecting elements turned axially also tovarying degrees. The operating handle being now turned, during the firstquarter turn the selecting elements are moved longitudinally, fromnormal lowered midway position, to position at one end' or the other ofthe strokes thereof and raised to effective start- 'ing position; duringthe next half turn of slidable dog or tooth 8, and having also atransversely extending pin 45, working in a slot 46 of the collar nextadjacent thereto at one side, the collar 42CL at one end of the seriesbeing fast to the shaft and all of the other collars having` usually africtional bind upon the shaft, to rotate therewith, but admitting of amovement of the collars with respect to the shaft against suchfrictional bind or resistance. rhe fast end collar and all of the othercollars have each a pin and slot, as stated. The dogs of all of thecollars are arranged spirally, entirely around the shaft in a singleseries.

1n the reverse or counter clockwise movement of the shaft, to rearrangethe teeth or dogs of the collars to reverse spiral, the fast end collar42a, all of the other collars 42 and the other end collar 42b will turnwith the shaft, the pin 45au being held temporarily from turning withthe shaft, by suitable means. Therefore,.this pin 45a will next arriveat the end of the slot 46 of the collar 42h, and will then check saidcollar 42b from further movement with the shaft, said collar havingmoved a distance equal to the length of the slot 46.

lThe pin 45 of the collar 421 being now checked with said collar fromfurther rotation with the shaft, the second collar 42 in line will movewith the shaft the length of the slot 46 thereof, when the end wall ofsaid slot will be brought against the pin 45 of collar 42D, to preventfurther movement with the shaft of said second collar in line, saidcollar having moved with the shaft a distance equal to the combinedlength of two slots 46. This step by step or successive checking of thecollars will follow in the reverse movement of the shaft throughout theline of collars, to the fast collar 42a, which will, when the spiralrearrangement is completed, have moved a dis-V tance equal to the sum ofthe length of all of the slots 46, the collar next adjacent thereto adistance equal to the sum of the length of all of the slots less thelength of one slot, etc.

rlhe collar 42a is made fast to the shaft by a pin s thereof engaging aradial notch s of an extra collar t, fast to the shaft.

' In the clockwise movement of the operating handle, the same actiontakes place to check the movement of the pin 45a with the shaft 9 whilerearrangement of the carrying teeth to reverse spiral is beingaccomplished.

Located between the intermediate gears 11 are reciprocatory carryingmembers 47, pivoted at 48 and having each an arm 49, normally extendingin the path of a transverse pin 50 of a registering wheel 5, eachregistering wheel having` a pin 50, and said member having an oppositelyprojecting arm 51, provided with a cam surface 52, adapted to extendwithin the path of movement of a carrying dog, there being one member 47for each dog and for each registering wheel.

The cams 52 of the arms 5l are each double, having two inclined camsurfaces, one of which acts upon the dogs to move them endwise in therotation of the carrying shaft clockwise, and the other oppositelyinclined part acting to move the dog endwise in the reverse spiralarrangement, the dogs moving endwise in the same direction into activeposition in eac-h case. rEhe dogs are returned to normal position bysprings 53 thereof (Fig. l2) and the pivoted carrying members arereturnec to normal position by radial projections or fingers 54 of thecarrying shaft, said fingers following the dogs and having end camsurfaces 55, engaging said members, the cams 55 being double, havingoppositely inclined parts, to return said members in eitl er directionof rotation.

The radial fingers 54 are loosely mounted upon the carrying shaft,between the collars thereof, each finger having a connection with theend of a pin of the second collar therefrom at one side thereof, andbeing movable with said pin and collar, in the rea 1rangement to reversespiral of the carrying dogs, to position at the opposite side of thecarrying dog of the adjacent collar at this side. The fingers, beingmover. to the opposite Sides of the carrying dogs, are in position toreturn the carrying members 47 to normal position after said membershave acted upon said dogs upon reverse movenent of the carrying shaft.

Located between the intermediate gears are collars 56, carrying each aspringpressed pin 57, said .pin engaging either of two recesses 58 ofthe pivoted carrying members, to retain them in normal position and inposition when thrown pivotally.

In order that, during the rotation of the registering wheels in settingup the problem, the carrying dogs shall not be moved endwise intoeffective position by those of the carrying members 47 that have beenpivotally thrown by the transverse pins of the registering wheels, andshall not, in the turning of the carrying shaft, engage and' turn theregistering wheels, it is provided that the carrying shaft shall bemovable toward and away from the registering wheels, the dogs upon saidshaft being movable therewith into position for engagement with saidcarrying members, said dogs being thereby slid into active position androtating the registering wheels upon the last portion only of the turnof the crank handle. For this purpose, the carrying shaft is mounted atthe outer end of one arm of bell crank levers 59, fulcrumed upon theshaft 23, the outer end of the other arms of said levers having pivotalconnection with the frame 21 at 60, whereby, as the frame is raised fromnormal lowered position, the lever is rocked, to rock the carrying shaftand its dogs away from the registering wheels, and as the said frame islowered, after the registering wheels have been rotated in Setting upthe problem, the carry ing shaft and its dogs are rocked toward theregistering wheels.

ln addition, the next item being set up by depressing certain of thenumeral keys, as those previously referred to, to add 999, the selectingelements will be turned axially, and the operating handle being rotated,said elements will be thrown longitudinally to rotate the units, tensand hundredths registering wheels nine teeth again, the transverse pinsof the units tens, and hundredths registering wheels engaging thecorresponding pivoted carrying members and throwing said memberspivotally to bring the earns- 52 of the arms 5l thereof into the path ofthe corresponding carrying dogs, said dogs, in the rotation of thecarrying shaft, being thereby slid endwise or transversely of themachine, into position to, upon further turning. of the carrying shaft,engage the teeth of the gears 11 corresponding to the tens andhundredths registering wheels and turn the same one tooth additionally,and engage the teeth of the gears 11 corresponding to the thousandthsregistering wheel and turn the same one tooth.

Means are provided to retain the shafts of the selecting elements inposition as axially turned, with the elements thereupon, in setting upthe problem, consisting preferably of a transverse bar 62 at the rear ofthe machine, said bar having depending fingers or teeth 63, said teethindividually engaging with the teeth of ten-tooth gears 61k, mountedupon the rear ends of the shafts of the said elements, said gears beingraised with the frame 21 to engage said teeth, and depressed with saidframe to disengage from said teeth.

Means are provided to indicate the number set up by axial turning of theselecting element corresponding to each denominational series of keys,consisting preferably of a crown gear 65 upon each of the shafts of thelselecting elements, said gear engaging a pinion 66 of an upright staE67, said sta carrying at its upper end a dial 68, bearing a series ofnumerals from 0 to 9 inclusive and registering with a sight opening 69of the top plate of the casing.

Upon the shaft 6 of the registering wheels 5 is located a second seriesof registering wheels 7, sight openings in the carriage exposing thenumber upon the latter wheels indicating the quotient in division andthe `multiplier in multiplication, as also the 4intermediate portion ofsaid pawl having a lateral pin 7 l engaging eccentrically a disk 75 uponshaft 76, said shaft having crown gear 77 in mesh with a spur gear 7 8upon shaft 27.
